JOHN A. RAFTER, OF HOLTON, KANSAS.

INHALER.

SPECIFICATION forming part of Letters Patent No. 594,966, dated December 7,1897.

Application filed May 29, 1897. Serial No. 638,775. (No model.)

To all whom it may concern/.-

Be it known that I, JOHN A. RAFTER, a citizen of the United States, residing at Holton, Jackson county, Kansas, have invented a new and useful Improvement in Inhalers, of which the following is a specification.

The invention relates to a device for heating and medicating atmospheric air for the treatment of ear, throat, nose, and lung diseases; and it consists of a simple, durable, and effective device, -to be fully hereinafter I v described.

The drawing is a side elevation of the device.

Reference-letter A represents an open-bottomed heating-chamber constructed, preferably, of thick metal and adapted to serve as a base or support for the device.

B B are tubes which project upwardly from the heating-chamber and at their upper ends support a chamber or cylinder 0. These tubes, as shown, communicate with the interior of the heating-chamber and cylinder and serve to conduct the vapors and hot medicated air from the former to the latter.

The cylinder 0 is designed to hold a packing of medicinal herbs and resins or disin fecting materials, or it may contain any medicinal preparation or compound the fumes or vapors of which it is desired to avail of in the treatment of the aforementioned diseases. A convenient means for holding the packing or compound in the cylinder consists in a tubular receptacle D, placed loosely within the cylinder 0 and over the upper and open ends of the tubes B B. By removing one end of the cylinder 0 this receptacle or holder can readily be placed therein or removed therefrom. As shown, the tubes communicate with the interior of the receptacle D.

E is a nipple formed in one end of the cylinder (l, and F is an inhaling-tube secured to the nipple.

G is a metallic cup to receive the preparation to be vaporized.

In using the device the receptacle or holder D is provided with the proper preparation, which can be placed loosely therein or caused to adhere to the inner walls thereof, if deface over the metal cup or other receptacle G and resting, as before stated, upon its thick-walled metallic base 'or heating-chamber. When the inhaler is well heated, the receptacle G will be found to be hot. It only remains now to place any suitable preparation or compound which is to be vaporized within the said receptacle. The hot medicated air and fumes or vapors from the capsule G and the heat-chamber A will pass through the tubes B B into the cylinder 0, combining therewith vapor from the medicinalcompounds contained therein and by it is modified and disinfected and rendered more efficient and useful.

What I claim as new, and desire to secure by Letters Patent, is

1. In an inhaler the combination of the open-bottomed heating-chamber adapted to cover or inclose the cup G, and to serve as a support for the device, with the cylinder 0, provided with the holder D, for inclosing medicinal compounds and healing agents, and an inhaling-tube F, projecting from said cylinder 0, and the tubes B, B, projecting upwardly from the heating-chamber and supporting'the chambers O, and D, and interiorly connecting the said chambers substantially as described.

2. In an inhaler, the open-bottomed heat ing-chamber adapted to serve as a support, and to inclose the metal cup G, the cylinder 0 provided with a holder D, for medicinal agents, and a nipple E projecting from the cylinder 0, and an inhaling-tube F, secured to, and projecting from the nipple E, and the tubes B, B, interiorly connecting the cham-.

her A, to the cylinder 0, and the holder D, all connected and arranged as is shown in the drawing, so that the vapor or fumes gen- JOHN A. RAFTE'R.
